Earnings have swung into focus in a big way, starting with Caterpillar CAT, -9.13% whose shares skidded 9.1% after the company missed fourth-quarter earnings estimates.

Trade will also be in the spotlight with talks aimed at resolving the impasse over Chinese technology ambitions and other issues expected to restart in Washington later in the week, headed up by U.S. Trade Representative Robert Lighthizer and Chinese Vice Premier Liu He.

U.S. President Donald Trump and Democratic congressional leaders agreed on Friday to reopen the government until Feb. 15, for now ending a 35-day partial shutdown. Lawmakers will debate funding for an extension of the southern border wall.

But fears of another shutdown remain after Trump, in an interview with The Wall Street Journal, said he placed a 50-50 chance of a deal over border-wall funding being reached by a newly created board of 17 before the next government-funding deadline.

What were strategists saying?
“The Nvdia profit warning is [hurting market sentiment] more than the Caterpillar earnings miss,” Larry Benedict, chief executive of the Opportunistic Trader told MarketWatch. “Slowing demand in China hit them hard,” he said, causing investors to worry that Chinese “demand has slowed more than people imagine.”

U.S. stocks are “starting this week under some pressure as Trump throws cold water on the chances of a shutdown deal, and after Chinese industrial production comes in light,” wrote Dave Lutz, head of ETFs at JonesTrading, in a note. Lutz highlighted elevated uncertainty with U.S.-China trade talks, the FOMC decision, the jobs report, and “angst” over the Brexit vote.
